SCX is a general-purpose high-precision
calculator that combines standard
mathematical functions with pricing
functions needed in the business/retail
world. It's designed for simplicity and ease
of use.

SCX 1.8 Features:

SCX has a large, easy to read 15-digit display with 30 digits of
internal
precision.

Errors during entry can be corrected with the Graffiti backspace
stroke.

The Cost/Sell/Margin buttons provide a simple way to determine
pricing
information.

The % function allows rapid discount and markup calculations.

The last-entered operator (+,-,x,÷) is highlighted, and can
be
repeated by pressing [=].

Keystroke equivalents allow SCX to be operated via Graffiti or an
external
keyboard.
